PANE FASTENER Filed June 3, 1936 Patented Mar. 7, 1939 PATENT v OFFICE J to the thickness of a pane.

Application June 3, 1936, Serial No. 83,313 In Germany November 1, 1934 4 Claims. (01. ios'1-o This" invention relates to a pane fastener for "four superimposed glass plates two of which extend in a single plane, with their mating corners out awayat an'angle to their edges andarranged parallel and spaced relation to each other. It "is anobjct of the invention to provide a fastener whieh faeilitates'the draining of rain water by so arrahging'thepartsof the fastener and of a paneholding plate connected thereto that the water is nowhere backed up.

To this end, the fastener, besides being equipped with a flange for engaging the top of a purlin, and a lug-at rightan-gles to the flange for engaging the front 'side ofthe purlin, has a web arranged at an angle 'to the -flange spaced from the lug for the thickness-of a pane and adapted to enter the space between the said cut-away corners. The thickness or: the web is less thanthat of a pane so that as the web is placed between the corners, a drain passage is' defined byv the web and the upermost pane. For spacing the uppermost pane from one of Lhepanes that are in a single plane, a rib' is provided at the lower edge of the web, the depth of the rib plus the thickness of the rib being equal This pane and the uppermost pane are supported by a pair of spaced projections arranged on the lower end of the web at the same side as the rib so that the water flows freely between the two projections.

Similar spaced projections or fingers are arranged at the inner side of the pane-holding plate.

In the accompanying drawing a fastener embodying the invention is illustrated by way of example.

Fig. 1 is an elevation of the fastener attached to a purlin.

Fig. 2 is an end elevation of the fastener, viewed from the left in Fig. 1.

Fig. 3 is a plan view of Fig. 1.

* Fig. 4 is an elevation, and

Fig. 5 is a plan View, of a pane-holding plate.

Fig. 6 is an elevation showing the four panes, the fastener and the holding plate assembled.

Referring now to the drawing, 9 is a purlin, and

I9 is a flange at the upper end of the fastener which is placed on the top of the purlin and is surmounted by a crest 2 I. A lug 22 for engaging the front side of the purlin and an inclined web II] are cast integral with the flange l9 and the crest 2|. The lug 22 is secured to the purlin by any suitable means, such as a screw 34.

The panes 2 and 3, Fig.6, are in a single plane and their mating corners are cut away at an angle of 45 degs. The cut-away corners define a space 8 between the panes 2 and 3 for the reception of the web 10. I is the lowermost, and l is the uppermost pane.

The inner face of the web is spaced from the lug 22 for a distance 23 equal to the thickness of a,

'pane, and the thickness of the web is about half that of the glass panes. At its lower end, the web ID has an extension 24 of the same thickness as the web which has outwardly directed projections 25 and 26. The projection 25 supports the glass, pane 3 in vertical direction, whereas the projection 26 lies between the cut-away corners of the panes 2 and 3 and in conjunction with a screw bolt l 6 on the web it! supports the corner of the pane 4. The extension 24 and the projections 25 and 26 thereon form ,a channel for the draining of the water.

The web' 10 has an outwardly projecting rib 21 extending along its lower edge in upward direction from the projection 26, making up the depth of the web, as described, and at its upper end extends vertically as far as the upper end of crest 2| in alignment with the vertical edge 28 of the pane'3.

"Ihe pane holding plate I! is of substantially triangular shape and has on one of its sides a downwardly bent rib 29 forming with the cutaway corner of the pane 4 a passage to allow the water to flow off. Thereare also two inwardly extending fingers 3| and 32, one at each end of the base of the plate H. The finger 3| supports the pane 4 in vertical direction and holds down the 30 pane 2. The projection 25 of the extension 24 bears against the finger 32 on the plate, whereas the projection 26 engages a recess 33 in the base of the plate.

It will appear that any water penetrating to the point of juncture is immediately conducted off.

I claim:-
